Abstract
This paper designs and studies a bidirectional chaotic secure communication system, A theoretical model and system architecture for bidirectional chaos synchronization are proposed. We also demonstrate the feasibility and safety of its communications. By utilizing the symmetry of both systems in communication, the robustness of the chaotic synchronization to dispersion and nonlinear effects is improved. Finally, the communication between the two sides anti-interception secure communication can be achieved through simulation, which proves the chaotic laser system is coupled to each other.
